It measures true amplifier power output up to 15,000 watts, AC/DC voltage, current, impedance, frequency, and power factor in real time. Ideal for tuning car audio systems and subwoofer enclosures, it ensures optimal sound performance with advanced features like phase difference measurement and auto-shutdown for battery conservation. ## Description The purpose of this tool is to enable the user to: Measure True Amplifier Power output into any load reactive or resistive Measure Common DC voltages Measure DC voltage drops during quick transients on cable runs or battery / charging systems Measure Impedance of speakers at any power or frequency from 20Hz - 1kHz (box rise) Measure Phase Difference between Voltage and Current into reactive loads (Power Factor) Find Tuning Frequency of subwoofer enclosures Tune subwoofer enclosures for maximum power transfer Measure AC Volts (amplifier output) Measure AC Amps (amplifier output) Measure apparent power (VA) output, Phase Angle, and Real Power (Watts) of audio amplifier, or consumption of appliances that run on AC power Measure Frequency of a Sine Wave Specifications DC Voltmeter: -100 Volts to +100 Volts AC Voltmeter: 0 - 150 VRMS AC Ammeter: 0 - 100 ARMS AC Apparent Power: 0 - 15,000 VA Power Factor: 50 - 100% Frequency: 10 - 20,000 Hz AC Impedance: 0 - 200 Ohms True Power Dyno: 0 - 15,000 Watts Auto-shut off timer: 8 - 10 minutes after ON button is pressed Battery self-test and display of condition when AMM-1 is initialized Review: Great product - This probably has all the best meter I’ve ever had the privilege of using and have you several does somebody has so many modes it’s hard to keep up with all of them functionality is there works as it should well worth the money Review: Don’t think about it … buy it - It’s a must get item if you are really into car audio This will save you time and headache by tuning and making sure everything is running like it supposed to ## Features - DC Voltmeter: -100 Volts to +100 Volts - AC Voltmeter: 0 - 150 VRMS / AC Ammeter: 0 - 100 ARMS - AC Apparent Power: 0 - 15,000 / VA Power Factor: 50 - 100% - Frequency: 10 - 20,000 Hz / AC Impedance: 0 - 200 Ohms - Real time wattage / True Power Dyno: 0 - 15,000 Watts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YM19YBS | | Best Sellers Rank | #171,101 in Electronics ( See Top 100 in Electronics ) #1,062 in Audio Component Amplifiers | | Brand | SMD | | Brand Name | SMD | | Color | Blue | | Customer Reviews | 4.5 out of 5 stars 21 Reviews | | Item Dimensions | 8 x 5.25 x 2.25 inches | | Item Weight | 0.41 Kilograms | | Item dimensions L x W x H | 8 x 5.25 x 2.25 inches | | Manufacturer | SMD / D'Amore Engineering | | Measurement Type | Multimeter | | Minimum Operating Voltage | 100 Volts (DC) | | Model | SMD-AMM-1 | | Part Number | SMD-AMM-1-2 FBA | | Power Source | Battery Powered | | Specification Met | CE | | Style | Compact | | Style Name | Compact | | UPC | 680220998334 | ## Product Details - **Brand:** SMD - **Color:** Blue - **Item Weight:** 0.41 Kilograms - **Power Source:** Battery Powered - **Style:** Compact ## Images ![SMD Audio Multi Meter/Hand Held Amplifier Dyno - Real time wattage Tester - Image 1](https://m.media-amazon.com/images/I/711IzaEm5RL.jpg) ![SMD Audio Multi Meter/Hand Held Amplifier Dyno - Real time wattage Tester - Image 2](https://m.media-amazon.com/images/I/71EPkY+VAIL.jpg) ![SMD Audio Multi Meter/Hand Held Amplifier Dyno - Real time wattage Tester - Image 3](https://m.media-amazon.com/images/I/71LflBljH1L.jpg) ![SMD Audio Multi Meter/Hand Held Amplifier Dyno - Real time wattage Tester - Image 4](https://m.media-amazon.com/images/I/71yvcrch4+L.jpg) ![SMD Audio Multi Meter/Hand Held Amplifier Dyno - Real time wattage Tester - Image 5](https://m.media-amazon.com/images/I/61hBii6LdkL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***N on May 3, 2026* This probably has all the best meter I’ve ever had the privilege of using and have you several does somebody has so many modes it’s hard to keep up with all of them functionality is there works as it should well worth the money ### ⭐⭐⭐⭐⭐ Don’t think about it … buy it *by A***R on October 11, 2023* It’s a must get item if you are really into car audio This will save you time and headache by tuning and making sure everything is running like it supposed to ### ⭐⭐ You'd think for how much you're spending *by N***. on March 29, 2022* So the probes that they sent with this item did not work I almost returned it but then I thought to myself try a different set of probes that I currently have already. Thank God I did because the concept is cool but for the money you think I could get a decent pair of probes not the cheapest probes they could find it's cool I don't know how accurate it is I should return it but I guess I'm going to keep it but you think that they would give you better probes dude you think it would be better quality dude Steve needs you ripping off people and you're making it hard for the community to get back into systems because your little items are expensive as hell shame on you ## Frequently Bought Together - SMD Audio Multi Meter/Hand Held Amplifier Dyno - Real time wattage tester - SMD Distortion Detector DD-1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/199967056-smd-audio-multi-meter-hand-held-amplifier-dyno-real-time](https://www.desertcart.co.uk/products/199967056-smd-audio-multi-meter-hand-held-amplifier-dyno-real-time) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
